Integrate the OIDC protocol into OMS Community Edition to implement SSO

Last Updated：2024-09-18 02:01:08 Updated

OceanBase Migration Service (OMS) Community Edition must be integrated with the OpenID Connect (OIDC) protocol to adapt to the OAuth 2.0 authentication center. Currently, only the authorization-code mode is supported. This topic describes the configurations to be updated to integrate the OIDC protocol into OMS to implement third-party single sign-on (SSO).

Obtain parameters from the authentication center

You must add your application to the third-party SSO service to obtain parameters required by OIDC, such as the application ID and key.

Parameter	Description
clientId	The client ID of the third-party application.
clientSecret	The client secret of the third-party application.
scope	The authorization scope. The value is a list of permission IDs separated with commas (,). `openid` must be included in the value. Example: `openid,profile`.
ClientAuthenticationMethod	The authentication method. Valid values: `client_secret_basic` (recommended) and `basic`.
jwk_set_uri	The endpoint used to retrieve the public key of the JSON web key (JWK) for decoding the JWK.
authorization_uri	The authorization `endpoint`.
token_uri	The `endpoint` used to obtain a token.

Configure a callback URL

If the third-party SSO system has a logon callback URL whitelist, you must configure the whitelist.

Set the logon callback URL to http://{serverDomain}/login/oauth2/code/oms, in which serverDomain is the domain name of the server where OMS Community Edition is deployed.

Deploy OMS Community Edition

This section describes how to log on to OMS Community Edition deployed on a single node. If you want to deploy OMS on multiple nodes in a single region or on multiple nodes in multiple regions, see the "Deploy OMS with the configuration file available" section of the Deploy OMS on multiple nodes in a single region or Deploy OMS on multiple nodes in multiple regions topic.

Prerequisites

The installation environment meets the system and network requirements. For more information, see System and network requirements.
You have created a MetaDB cluster for OMS Community Edition.
You have obtained the installation package of OMS Community Edition, which is generally a tar.gz file whose name starts with oms.
You have loaded the installation package of OMS Community Edition to the local image repository of the Docker container.

docker load -i <Installation package of OMS Community Edition>
You have prepared a directory for mounting the container of OMS Community Edition. In the mount directory, OMS Community Edition will create the /home/admin/logs, /home/ds/store, and /home/ds/run directories for storing the component information and logs generated during the running of OMS Community Edition.
(Optional) You have prepared a time-series database for storing performance monitoring data and DDL/DML statistics of OMS Community Edition.

Procedure

Log on to the server where OMS Community Edition is deployed.
(Optional) Deploy a time-series database.

If you need to collect and display OMS monitoring data, deploy a time-series database. Otherwise, you can skip this step. For more information, see Deploy a time-series database.

Run the following command to obtain the deployment script from the loaded image:

sudo docker run -d --net host --name oms-config-tool <OMS_IMAGE> bash && sudo docker cp oms-config-tool:/root/docker_remote_deploy.sh . && sudo docker rm -f oms-config-tool

Here is an example:

sudo docker run -d --net host --name oms-config-tool work.oceanbase-dev.com/obartifact-store/oms:feature_3.4.0 bash && sudo docker cp oms-config-tool:/root/docker_remote_deploy.sh . && sudo docker rm -f oms-config-tool

Use the deployment script to start the deployment tool.
```
bash docker_remote_deploy.sh -o <Mount directory of the container of OMS Community Edition> -c <Address of the existing config.yaml configuration file> -i <Host IP address> -d <OMS_IMAGE>
```
The deployment tool of OMS Community Edition automatically verifies the CPU, memory, and disk resources. If any resource item does not meet the requirement, the deployment tool will display a message prompting that insufficient resources will affect the data migration speed.
Complete the deployment as prompted. After you set each parameter, press Enter to move on to the next parameter.
1. Select a deployment mode.
  
  Select Single Node in Single Region.
2. Select a task.
  
  Select Use Configuration File Uploaded with Script Option [-c].
3. If the system displays The specified database names already exist in the MetaDB. Are you sure that you want to continue?, the database names you specified already exist in the MetaDB in the original configuration file. This may be caused by repeated deployment or upgrade of OMS Community Edition. You can enter y and press Enter to proceed, or enter n and press Enter to re-specify the settings.
4. If the configuration file passes the check, all the settings are displayed. If the settings are correct, enter y and press Enter to proceed. Otherwise, enter n and press Enter to modify the settings.
  
  If the configuration file fails the check, modify the configuration information as prompted.
5. Specify the directory to which the container of OMS Community Edition is mounted in the host.
  
  Specify a directory with a large capacity.
6. Confirm whether the image file of OMS Community Edition can be named as OMS_IMAGE.
  
  If yes, enter y and press Enter to proceed. Otherwise, enter n and press Enter to modify the settings.
7. Determine whether to mount an SSL certificate to the container of OMS Community Edition.
  
  If yes, enter y, press Enter, and specify the https_key and https_crt directories as prompted. Otherwise, enter n and press Enter.
8. Start the deployment.

If you want to modify the configurations after the deployment, log on to the container of OMS Community Edition and perform the following steps:

Modify the config.yaml file based on business needs.
Run the python -m omsflow.scripts.units.oms_init_manager --init-config-file command.
Run the supervisorctl restart oms_console oms_drc_supervisor command.
